When my house was built, the gas cooktop was vented out through the slab by an 8" PVC pipe which was just left as an open bricked in hole in the ground. I covered it with a metal chimney cap to keep pests out, but every winter the cold air blows in through the downdraft on the stove.This 8" damper slid right into the PVC pipe perfectly creating an excellent seal and opens properly when the down draft exaust fan turns on. When the fan stops the damper shuts tight and no more drafts in the kitchen.

I installed this in the ductwork from a bathroom fan that I recently put it that has a damper that does not seal very well. Since my duct run was mostly horizontal this damper would not close 100% of the time and would let a small draft in. I had to take the damper apart and flip the spring around a put a half turn on it to help close the damper doors more securely. I think my bath fan is only an 80 cfm unit it still opens the damper fine. If this is installed in a vertical orientation and gravity would help close it I think it would work fine. Other option is to find a slightly stronger spring.

Comments about RSK Series 6" Duct Backdraft Damper:
I added a portable heat pump to my garage that requires ducting outside. This unit works great to prevent outside air infiltration.
Good for horizontal or vertical use
from Keene, NH
We installed a through the wall fan and used this backdraft damper. Because it has a spring to assist in closing the damper, it works in the horizontal orientation. This works very well and it avoids a cold air draft coming back into the house when the fan is off.
Damper worked great

Just what I needed - fast shipping
Used for additional back-draft protection for Range Hood and bath exhaust fan.I love this is slips inside duct work. The price was very reasonable.The shipping was so fast I couldn't believe it - less than 24 hours in my case.

Better than Most
from Woodbridge, NJ
Better than most for backdraft protection installed at the output of a bathroom ventilation fan. If used in a horizontal duct, be sure to turn it so that the rod the two flappers pivot on are in a vertical position so that the upper flapper does not have to fight gravity to close fully.
